摘要:

现实的和符合理论约束的双重部分子分布模型对于可靠地描述双重部分子散射是至关重要的。我们展示了如何一步一步地改进在部分子之间的小横向距离的限制中具有正确行为的anadian,例如以10%左右的精度满足双部分子分布的求和规则。

英文摘要:

Models for double parton distributions that are realistic and consistent with theoretical constraints are crucial for a reliable description of double parton scattering. We show how an ansatz that has the correct behaviour in the limit of small transverse distance between the partons can be improved step by step, such as to fulfil the sum rules for double parton distributions with an accuracy around 10%.
